Abstract
Methods of making metal bond abrasive articles via powder bed jetting are disclosed. Metal bond abrasive articles prepared by the method include abrasive articles having arcuate or tortuous cooling channels, abrasive segments, abrasive wheels, and rotary dental tools.
Claims14
A metal bond abrasive article comprising a metallic binder material having abrasive particles retained therein, wherein the metal bond abrasive article has at least one tortuous cooling channel extending at least partially therethrough, and wherein the abrasive particles comprise first abrasive particles and second abrasive particles, wherein the first abrasive particles and second abrasive particles are disposed in interspersed predetermined different regions within the metal bond abrasive article.
A rotary dental tool, wherein at least a portion of the dental tool comprises abrasive particles dispersed and retained in a porous metal bond matrix comprising sintered metal particles, wherein the dental tool is a dental bur and wherein the rotary dental tool comprises a porous metal-containing matrix having a void fraction of 15 to 50 volume percent.
A metal bond abrasive article comprising a metallic binder material having abrasive particles retained therein, wherein the metal bond abrasive article has at least one tortuous cooling channel extending at least partially therethrough and wherein the metal bond abrasive article comprises a porous metal-containing matrix having a void fraction of 15 to 50 volume percent.
